Hi,
I think I'm having the same issue:
Linux ricardo-N24-25BU 4.8.0-28-generic #30-Ubuntu SMP Fri Nov 11
14:03:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.10
Release: 16.10
Codename: yakkety
Just upgraded to 16.10 last night, after bootup, I connect to a work VPN
(OpenVPN + Pritunl) which was working ok so far.
route -n shows the new routes, and resolve.conf is correctly updated
with the VPN DNS nameserver
Any direct query: dig, nslookup, ip route get {host} resolves correctly
using the VPN DNS
But any other command: ping, telnet, mysql, etc resolves without the VPN
DNS (unless instructed otherwise explicitely)
Quick solution was:
sudo systemctl restart systemd-resolved.service

Title:
systemd-resolved breaks VPN with split-horizon DNS
Status in systemd:
New
Status in systemd package in Ubuntu:
Confirmed
Bug description:
I use a VPN configured with network-manager-openconnect-gnome in which
a split-horizon DNS setup assigns different addresses to some names
inside the remote network than the addresses seen for those names from
outside the remote network. However, systemd-resolved often decides
to ignore the VPN’s DNS servers and use the local network’s DNS
servers to resolve names (whether in the remote domain or not),
breaking the split-horizon DNS.
